CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 496,849, dated May 9,1893. Application filed April 26, 1892. Serial No. 430,799. (No model.)

To all whom iv' may concern/.-

Be it known that I, PHILIP BOGLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Couplings; and I dohereby declare the following to be a full, clear, and exact descriptionof thek invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

Thisinvention relatestoanovelconstruction in automatic car couplingswhich comprise two mutually grasping heads of similar construction thatare arranged in the ends of each car, and the invention consists in thefeatures of construction hereinafter fully described and specificallyclaimed.

In the accompanying drawings illustrating my invention,-Figuie 1 is aview partly in elevation and in section of the end portions of two carsprovided with couplings constructed in accordance with my invention andshown in side elevation in their mutually grasping position. Fig. 2 is avertical sectional view on the line 2-2 of Fig. 3. Fig. 3

is a horizontal section on the line 3-3 of Fig. 2. Fig. 4 is a verticalcross section on line 4-4 of Fig. 2. Fig. 5 is an end elevation of a carand uncoupling devices.

Referring now to said drawings, A indicates the lioor beams of a car, Bthe flooring, C the endcross beams, and D the vdraw-bar beams locatedbeneath the floor beams A. The said draw-bar beams D are parallel witheach other and extend back from the end of the car in an obvious manner,and are provided on their adjacent side faces with guide plates 1securely bolted or riveted thereto. Between the rear end portions ofsaid guide plates 1 is located a cross piece or guide 2 that is securedat its sides to said guide plates and is provided with an opening orperforation 3 to receive the pin 4 carried by the draw-bar E and bufferblock 5. The said draw-bar E is connected at its rear end with saidbuifer block, and the rear end portions of said draw.

apertures 6 and 7 in the ends of the buer piece or guide are arrangedthe buffersprings 8 which act in thel usual manner to cushion the shockor impact to which the coupling may be subjected, and it will be notedthat said bilder block is free to move back to compress the springs 8,while itsforward movement is limited to the extent shown in Figs. 2 and3, by nuts 9 upon the rear end of pin and in the rear of guide 2 and acollar l0 secured to said pin between the end of the draw-bar and thebuffer block. t

My coupling is constructed upon what 1s known as the arrow-headprinciple, that is to say the front end of the draw-bar is provided with.an arrow-head embracing an upper and lower barb 11 and 12. The end ofsaid arrow-head is provided with a recess. 13 to receive the end of anordinary coupling link, and with two openings 14 above and beloW thesaine for the reception o f a coupling pin, whereby a car provided withmyv coupling can be coupled with oars having other couplings. In therear of the said barbs 11 and 12 of the arrow head, the draw-bar isprovided with upwardly and downwardly extending lateral wings orprojections 15 and 16;

It is of course obvious that means must be provided for normally holdingthe draw-bars in a horizontal position but which permit a verticaldeflection thereof to accomplish the coupling and uncoupling operations,and to this end the drawbar is providedon its upper and lower faces justin front of its connection with the buii'er block, with two sockets 17and 18, which receive the ends of two springs 19 and 20, which bear attheir other ends respectively against a plate 21 on the lower face ofthe end cross beam C, and upon a bearing plate 22 secured to saiddraw-bar beams D. The said springs 19 and 2O serve to hold the draw-barin horizontal position, and to permit the vertical d'eiiection thereof,the pin 4 has a pivotal connection with said guide 2 by reason of thechamfered edges of said aperture 3 in said guide, and the chamferedWasher 23 located upon said pin betweenv the nuts 9 and the rear face ofthe guide.

When the two arrow heads are in their mutually grasping position asshown in Fig. 1, the rear faces of two of the barbs are in en- IOOgagement with each other, with the hat upper and lower faces 24 and 25,respectively, resting against the face of the draw-bar in the rear ofthe barb, while the end of the arrow The devices for uncoupling the twocoup- 1ers are constructed as followsz-ln the rear of the barbs 11 and12, the draw-bars are open at top and bottom, as at 26 and 27, and ashaft 28 extends longitudinally through the draw-bar from the headthereof in which is formed a bearing 29 for the end of said shaft. Invertical alignment with the openings 26 and 27 in the head of thedraw-bar, said shaft 28 is provided with two upwardly inclined and twodownwardly inclined arins'30 and 3l (Figs. 2, 3, and 4) whose ends arenormally located near the upper and lower faces of the draw-bar and nearthe outer sides of said openings 26 and 27. The shaft 28 bears inanother bearing 32 near the rear end of the draw-bar, and through anopening 33 in the upper side of said draw-bar an arm or lever 34 that isrigidly secured to said shaft 28, so that by moving said lever 34 theshaft will be rocked to throw the arms 30 and 3l up and down through theopenings 26 and 27 against the straight edge of the barb of the arrowhead in engagement therewith, and thereby separate the two couplings inan obvious manner.

In Figs. 4 and 5 I have shown devices for swinging the lever 34 fromeither the sides or top of the car. A horizontally sliding bar 35 islocated in guides 36 on the `end of the car, and is connected by meansof a link 37 with the lever 34, so that by sliding said bar 35 in eitherdirectiontlie lever will be moved to uncouple the cars.

The device for iincoupling the cars from the top consists of an uprightlever 37 pivoted to the end of the car and having itsvupper end locatedadjacent the brake wheel, while to its lower end is pivoted a link 38that is also pivoted to the sliding bar 35, so that by swinging theupper end of the lever 37 the couplers can be disconnected through theintermediacy of connections described.
